摘要
Objective The -455 G/A(HaeIII)polymorphism of β-fibrinogen gene influences levels of plasma fibrinogen. We further investigated whether it influences the risk of ischemic cerebrovascular disease. Methods We accumulated 134 acute ischemic cerebrovascular disease(ICVD)cases and compared their -455 G/A status with a control group(n = 166). The β-fibrinogen gene -455 G/A polymorphism was analyzed for all subjects by PCR-RFLP with the restrictive enzyme HaeIII. Results Plasma fibrinogen was higher in AA homozygous participants(341 mg/dL)than in partici-pants carrying the G allele: GA(290 mg/dL), GG(298 mg/dL)in the control group. Plasma fibrinogen was also higher in AA homozygous patients(353 mg/dL)than in cases carrying the G allele: GA(287 mg/dL), GG(302 mg/dL)in the ICVD group. However, there was no significant association between β-fibrinogen gene -455 G/A polymorphism and ICVD group. Conclusions Although a small effect cannot be excluded, β-fibrinogen gene -455 G/A polymor-phism is an independent predictor of plasma fibrinogen, but not of ischemic cerebrovascular disease.
